Currently, in the Republic of Moldova about 94.4% of livestock is in small scale farms (small holdings), which makes it difficult to collect, store and use produced organic wastes. As a result, huge quantities of unused manure are thrown to the edge of roads, ridges, rivers, which leads to soil and water pollution. At the same time, soils involved in agricultural production are affected by various degradation processes, most of which are related to the lack of organic material and nutrients. The goal of the research was to reveal the possibility of manure use at local scale and to determine suitable sites for utilization of manure as organic fertilizer on example of Grinauti village, Riscani district in order. The selection was made by use of GIS technologies, namely through construction of GIS based decision model using Boolean logic. For decisional model construction were used eight decisional criteria relevant to study goal: soil bonitet; soil mobile phosphorus content; slope; proximity to access ways; proximity to springs and wells; proximity to localities and sheepfolds; proximity to aquatic objects; land use. In the result it was obtained a map of favorable places for use of manure. According to obtained decisional model 77.9% of arable areas are suitable for manure application.
